Improper handling and installation can permanently dam-age a sprinkler system or its compo-nents and cause the sprinkler to fail to operate in a fire situation or cause it to operate Services 800-381-9312 | +1-401-781-8220 Description The TYCO Series DS-1, K-factor, 3/4 and 1-Inch NPT, Quick response , Standard Coverage , Dry-Type Sprink-lers are decorative, 3-mm glass bulb automatic sprinklers de signed for com-mercial use.

2 Dry-Type Sprinklers are typically used where: pendent sprinklers are re quired on dry pipe systems that are exposed to freezing tempera tures; for example, sprinkler drops from un heated por-tions of buildings. sprinklers and/or a portion of the con-necting piping are exposed to freezing temperatures; for example, sprinkler drops from wet sys tems into freezers, sprinkler sprigs from wet systems into unheated attics, or horizontal piping extensions through a wall to protect an unheated areas such as loading docks, overhangs, and building exteriors. sprinklers are used on sys tems that are seasonally drained to avoid freezing; for example, vacation Series DS-1 Dry-Type Sprinklers described herein must be installed and maintained in compliance with this document, as well as with the applica-ble standards of the National Fire Protection Association, in addition to the standards of any authorities hav ing jurisdiction.

3 Failure to do so may impair the performance of these de vices. Owners are responsible for maintain ing their fire protection system and de vices in proper operating condition. The in-stalling contractor or sprinkler manu-facturer should be contacted with any questions. The Series DS-1 Dry-Type Sprinklers must only be installed in fittings that meet the requirements of the Design Criteria section.

9 See Figures 1 and glass Bulb contains a fluid that ex-pands when ex posed to heat. When the rated tem perature is reached, the fluid expands sufficiently to shatter the glass Bulb, and the Bulb Seat is released. The compressed Spring is then able to ex pand and push the Water Tube as well as the Guide Tube outward. This action simultaneously pulls inward on the Yoke, withdrawing the Plug with Sealing Assembly from the Inlet and allowing the sprin kler to activate and flow water. Design CriteriaThe TYCO Series DS-1 Sprinklers are intended for use in fire sprinkler sys-tems designed in accordance with the Standard installation rules recognized by the applicable Listing or Approval agency; for example, UL Listing is based on NFPA 13 requirements.

10 Sprinkler FittingsInstall the 3/4 or 1-inch NPT Series DS-1 Dry-Type Sprinklers in the 3/4 or 1-inch NPT outlet or run of the follow-ing fittings: malleable or ductile iron threaded tee fittings that meet the dimensional re-quirements of ANSI (Class 150) cast iron threaded tee fittings that meet the dimensional requirements of ANSI (Class 125). Do not install the DS-1 Sprinklers into an elbow fittings. The Inlet of the sprin-kler can contact the interior of the el-bow, potentially damaging the Inlet unused outlet of the threaded tee is plugged as shown in Figures 12 and 13. You can also install the Series DS-1 Dry-Type Sprinklers in the 3/4 or 1-inch NPT outlet of a GRINNELL Figure 730 Mechanical Tee. However, the use of the Figure 730 Tee for this arrangement is limited to wet pipe configuration shown in Figure 12 is only applicable for wet pipe systems where the sprinkler fitting and water-filled pipe above the sprinkler fitting are not subject to freezing and where the length of the Dry-Type Sprinkler has the minimum exposure length depicted in Figure 11.
